PARKER,n 0F BIRMINGHAM, MICHIGAN, ASSIGNOR TO GENERAL MOTORS COR- PORATION, OF DETROIT, MICHIGAN, A CORPORATION OF DELAWARE RUBBER ENGINE SUPPORT Application led January 4, 1929. Serial No. 330,382.

This invention relates to resilient supports and more particularly to an improvement in cushion mount-ings especially adapted for mounting an internal combustion engine in the chassis frame of a motor vehicle.

Practically every internal combustion en.

vibrations so that the disagreeable and harmful effects of vibrations are eliminated.

It is also an object of the invention to provide a mounting for cushioning shocks and stresses in all 'directions whereby either horizontal or vertical vibrations are damped out, and the engine itself freed from strains incidnt to road shocks, frame weaving and the li e.

Another object of the invention is to proinexpensive structure which will facilitate production assembly of vehicles and readilypermit subsequent re` moval and replacement of the engine in the chassis wit-hout disturbing the relation of the mounting parts.

Additional objects and advantages of the `invention will be apparent from the following specification when taken in connection with the accompanying drawing wherein Fig. 1 is a fragmentary top plan view of a chassis frame having an engine' mounted therein in 'accordance with the present inventi'on. 4

Fig. 2 is a side elevation of a portion of the chassis frame with parts broken away to show the support.'

Fig. 3 is a vertical sectional view taken on line 3-3 of Fig. 2 and. Fig. 4 is a sectional view of the chassis frame and a supporting bracket and is taken on line 4-4 of Fig 2.

In the drawings, illustrating the preferred embodiment of the invention, the numerals 1-1 indicate a pair of longitudinally extending channelshaped chassis frame members and Qiis an internal combustion engine to .be supported in the frame. The engine shown in the drawings is of the V keight cylinder type, which consists of two banks or rows of four cylinders each, arranged at an angle to eachother and having pistons connected to a common crankshaft, but it will be evident that other types of engines may be mounted 1n the chassis frame by means of the present invention. Any suitable form of mounting may be used at the front of the engine, and if desired this front mounting ma be the same as that illustrated at the rear. ecured within the channel of each frame member 1 opposite the iywheel housing 3 is a bracket 4 consisting of a vertical web having a marginal flange 5 at its side, a top fiange 6 riveted or otherwise secured to the to fian e'of the frame member and 'a bottom ange secured as by riveting to the lower ange of the frame member. The bracket also has a lateral earl 8 which may be riveted to the vertical side wall of the frame memberl. Intermediate its" height the bracket 4 is provided with a semi-spherical portion 9 affording pocket or depressionwith which cooperates asimilar pocket or depression formed in a cover or cap 10 removably secured by bolts 11 to bracket 4.

Secured within the opening formed by the similar elastic deformable material, the other i portion of which bushing extends axially between adjacent surfaces of the inner vand outer vmembers and between 'an end iange 14H-15 and the intermediate enlargement 13.

the spool and having screw threaded engagement with the nut 19 located in a de ression in the inside wall of the flywheel ousing and secured in place by a set screw 20. Aligned with the opening through the spool 12 1s an openin 21 in the vertical web of the frame mem er an'd through which the head of the bolt 18 extends, the opening being suciently large to permit engagement with the bolt head of a spanner wrench or other toolfor the manipulation of the bolt into and out of engagement with the nut 19. One or more shims such as indicated at 22 may be inserted between the flange and flywheel housing 3 to properly locate the ene in the chassis frame. After the bracket 4 is fastened to the frame member-1, the spool 12 and elastic bushingsv 17 are secured in place by the retainer cap 10, the bolts 11 bein drawn up to place the elastic bushingseun er an initial predetermined pressure which materially increases the a0 life of the rubber substance and" also eliminates its excessive responsiveness to deformation. When the engine is to be mounted in the frame it is only necessary to swing 1t into proper position and insert the bolt 18through the spool 12 and then turn the bolt into screw threaded engagement with the nut 19. Of course this procedure can be varied and if desired the spool can first be mounted on the flywheel housin and subsequently fastened to the bracket. hould it later become necessary, after the vehicle has been in use, to remove the engine this may be done by simply unthreading the bolt 18 without disturbing the assembled unit or the relation of the inner and outer members and the redetermined compression of the rubber bus ings.

While only a preferredl embodiment has been illustrated, it will be understood that the invention is not limited to the specific details described, but that such modifications may be made'as come within the scope of appended claims.

I claim:
